ovulation first month

I started taking my birth control on the 3rd day of my last period (January 15). i’m in the middle of my first pack right now and it feels like i’m ovulating??? I was told that I would be protected after 7 days so I’m not sure why i’m still ovulating, but now i’m scared. I was having sex with my boyfriend right before i started this feeling of ovulation and now i’m afraid if i am ovulating, that i will get pregnant. He pulled out, but that’s not to say that i’m completely clear from pregnancy because we didn’t use a condom. help please. also: i have taken the pill at the exact same time religiously since i have started it so that is not my issue, and i haven’t missed a pill once. thank you in advance
